BALINT PICTURE TUBE MOUNTING 3 Sheets-Sheet 5 Filed June 2, 1965 United States Patent 3,317,172 PICTURE TUBE MOUNTING John Balint, Langhorne Manor, Pa., assignor to George K. Garrett Company, Division of MSL Industries, Inc., Philadelphia, Pa., a corporation of Minnesota Filed June 2, 1965, Ser. No. 460,640 Claims. (Cl. 248-316) The present invention relates to a picture-tube mounting, whereby the picture-tube may be detachably secured to the enclosing cabinet or casing of a television receiver and held securely and safely in place with good distribution of the clamping forces and with sutficient flexibility in the mounting to minimize the strain upon the wall of the picture-tube incident to its mounting and securement to a cabinet or a casing.

The object of the present invention is flexibly and adjustably to mount or secure the picture-tube to the cabinet in a detachable manner with good distribution of clamping forces upon the tube and with uniformity of mounting in the assembly-line or mass-production of television receivers and to retain the transparent protective plate in the spaced relation to the face of the picture-tube.

Wih the above and other objects in view which will appear more fully from the following description and accompanying drawings, the present invention comprises which is sufiiciently flexible and bendable to conform itself to the rectangular (or other) shape of the front portion of the periphery of the picturetube near the face thereof (namely that part of the periphery of the picture-tube in which the cross-section thereof normal to its axis is uniform), worm-and-slot band-tightening means between the ends of the band to draw the ends together to the desired tightness around the picture-tube, and sheet metal mounting brackets at four or so selectively distributed points along the band and held between the band and the periphery of the picturetube, whereby the picture-tube may be detachably mounted to the cabinet by screws, or other fastening means connecting the brackets with the cabinet or housing.

In the accompanying drawings, characters indicate like parts,

FIGURE 9 represents a fragmentary rear perspective view of a picture-tube with the clamping-band and with a mounting-bracket of another embodiment of the present invention.

FIGURE 10 represents a rear perspective view of the bracket shown in FIGURE 9.

FIGURE 11 represents a rear elevational view of the same.

in which like reference 3,31 7,1 72 Patented May 2, 1 967 FIGURE 12 represents a side elevational view of the same.

The clamping-band designated generally by the numeral 1 is in the form of a flat strip or band of steel (or other suitable metal) of suflicient flexibility and deformability to conform to the aforementioned periphery 2 of the picture-tube 3 and having worm-engaging notches or slots 4 along the terminal portion 5 thereof and having a wormhousing 6 secured to the other end 7 thereof; there being a space or clearance between said worm-housing 6 and the end 7 of the band 1, in which clearance the slotted end 5 of the band 1 is adapted to pass, with the slots 4 thereof interme'shed with the worm 8 revolvably mounted within the worm-housing 6, as indicated in FIGURES 6 and 7.

By turning the outer end 9 of the stern of the Worm 8, the slotted end 5 of the band 1 may be moved into greater or lesser overlapping relation with the end 7 of the band 1, so as to contract or expand the closed loop so formed by said band and thus tighten the band onto the uniform cross-sectioned front portion 2 of the picture-tube 3 to the extent desired for clamping the picture-tube within such loop with a circumferentially distributed force adequate for its mounting to the cabinet and yet not so great as to place undue strain upon the picture-tube.

Each of the brackets, designated generally by the numeral 10, has a base portion 11 which overlaps the band 1 and is disposed between the band 1 and the peripheral portion 2 of the picture-tube 3, as indicated in FIGURES 2 to 5, and is held against the picture-tube by the clamping force of the band 1.

In the embodiment shown in FIGURES 2 and 3, the bracket 10 is not permanently secured to the band 1 but is instead provided with a rear base-tab 12 bent upwardly from its base 11 and a front base-tab 13 bent out of its base 11. The tabs 12 and 13 are spaced from each other (in a fore-and-aft direction) just sufficiently to accommodate the width of the band 1, so that the band 1 nests between said tabs.

In the embodiment shown in FIGURES 4 and 5 the base 11 is permanently secured to the band 1 by rivets 14 or by being spot-Welded thereto. The bracket 10 and band 1 may also be riveted to each other by extruding from or pressing out of one of these two members a small rivet-like projection and forming a registering hole in the other member, and then passing such projection through the hole and riveting it over to serve as a securement between the two members.

The bracket 10 includes a forwardly and outwardly angled or outwardly offset base-extension 15 which extends from and is formed in direct continuation of the front edge of the band-overlapping base 11. The bracket 10 further includes a generally vertical and generally U-shaped singleply mounting plate 16, extending outwardly from the front edge of the base-extension 15, and with the U-shape thereof inverted with respect to the base-extension, and with the ends of the legs of such U-shape formed in direct continuation of the base-extension 15.

'From the vertical mounting-plate 16 of the bracket 10 a shield-retainer or tab 17 is pressed outwardly and is formed in the manner indicated in FIGURES 3, 5, 12 and 10. This tab 17 has an inwardly extending hook-like terminal portion which is disposed at an angle to the baseextension 15, as indicated particularly in FIGURES 3, 5 and 12. The shield-retainer or tab 17 serves to retain the safety-shield in front of the picture-tube.

A screw or bolt receiving slot or hole 18 is provided in the mounting-plate 16, through which a bolt or screw is extended for detachably securing the bracket 10 to a cabinet 19 in the manner indicated in FIGURE 1.

By means of the so illustrated picture-tube mounting, the picture-tube is held securely in place, yet with sufiicient flexibility or adjustability in the mounting thereof not only to aid in the distribution of the clamping forces but also to minimize strain upon and damage to the picture-tube.

In FIGURE 8 a modified embodiment is shown, wherein the loop which encircles the picture-tube is made of two bands 1-a and ll-b of steel (or other suitable metal), with two adjustable worm connections. Each of the two half-loops (ll-a and 1-b) may have a worm-housing 6 (and worm therein) at one end thereof and worm-engaged slots 4 at the other end thereof, or, in the alternative, one of the half-loops (1-a or 1-b) may be a band with wormengaged slots 4 at both ends thereof, the other half-loop then having the two worm-housings 6 (and worms therein), namely, one at each end thereof.

The worm-housing 6 includes a lower housing member 6-11 and an upper housing-member 6-b. The lower housing member 6-a has side-flanges 20 with rivet-like projections 21 standing upward therefrom. The upper housing member 6-!) has corresponding aligned holes of the sidefianges 22 thereof through which the rivet-like projections 21 extend, by which the two housing members 6a and 6-12 are riveted to each other as indicated in FIGURES 6 and 7. The lower housing member 6-a is spot-welded to the inner or lower surface of the end 7 of the band 1, as indicated at 23 in FIGURE 7.

In the embodiment shown in FIGURES 9 to 12, a hole 18 is provided in the vertical panel 16, while the tab 17 is pressed out of the area 25 of the main panel 16. In this embodiment the base or saddle portion 11 is curved to correspond to the curved corner portion 26 of the picture tube, and the tab 13 is connected to the saddle 11 as indicated in FIGURE rather than being connected to the opposite longitudinal edge of the hole 27 (from which the tab 13 is struck) as in the embodiment shown in FIGURES 2 and 3.
